I do not believe there is information in the mp3 header that tell you how long it actually is (I think this is just a fluke.. or maybe they figured "Oh, they can just calculate it").
You have to get the bitrate (say, 128 kbps) and then find out the total size of the mp3.. and use that to calculate what the runtime will end up being.
